[Coco] Speed question

[Bob Devries]

Gary,

I'm running NitrOS9 version 3.2.6 on a Coco3 with 1MB ram. I ran that 
programme in a standard 80x24 text screen.

As far as I know, there should be no significant differences between the 
Aussie Coco and the USA one. There are *some* timing differences, but these 
are slight.
